The first digit can be selected in 8 species. The second point can be selected in 7 species. The third digit can be selected in 6 ways. The fourth digit can be chosen in 5 ways. The fifth point can be selected in 4 different ways.

Consequently, no. Alliance barrier = 8 * 7 * 6 * 5 * 4 = 6720.

Or, you know, you have 8 numbers on each wheel, and no numbers can be repeated. You need a 5-digit code. College does not count as 12345 is not the same as 21,345. However, nPr, where n is the total number of objects and R is the number of selected items. nPr is the name for a permutation. nPr = n! / (N - r)! Therefore, there are 8-digits, and I want a 5-digit number.

Repeats not allowed an object or a finger (can only be chosen once). Orders must be imported (123 is not the same as 213 in a permutation, but if it was a partnershipmbination means 123, the same as 213). r objects, one at a time, must be chosen from n objects.
